Hi, I was looking throught the forum since i have exacly the same question.
I have solved some mystery caches and i entered the corrected coordinates on the GC.com site.
On the geocaching maps (on gc.com) the icon and location is changed to the new location and another icon.
In L4C the location is changed, but it's stil the default mystery cache icon.
When i reload the single cache, the icon in L4C changes to a green icon and the corrected coordinates are listed in the cache information. refresh of a complete pocket query (with 1000 caches) takes a long time. But after a refresh of all the caches (and a reload of the database) the icons are green and the corrected coordinates are listed.
So it looks like the corrected coordinates are not correctly transferred from the pocket query to L4C. They are read as the normally listed coordinates for the mystery cache.
OR the corrected coordinates are not seand as corrected coordinates in the pocket query.
It would be great when a corrected coordinate when loaded from a pocket query is correctly listed as a coorcted coordinate and the icon is green.
